Virtual reality is amazing, but until now accessing it meant tethering yourself with a thick wire and a pricey startup kit. Cutting the cord was possible thanks to the Gear VR, but required and expensive smartphone to use as a display. All that has changed. Oculus is back again with the most accessible gateway to VR yet: the Oculus Go. It's portable, has thousands of apps, and doesn't require a smartphone - all for $199.
